A full review of Scotland's national transport strategy (NTS) should take place during the next Scottish Parliament, the transport minister has said.

Derek Mackay said the review would "delve into more fundamental questions" around transport priorities.

Sustainable transport campaigners however branded the last ten years a “wasted decade”.

Mr Mackay launched a "refresh" of the 2006 national transport strategy, which takes stock of the Scottish Government's performance so far and provides updates.

He said £15 billion has been spent on transport since 2007, with investment in key infrastructure such as the new Forth crossing and the railways.

He said: "Since 2006 we have made real progress, despite unforeseen circumstances such as a major financial crisis and recession, and we have invested heavily in transport infrastructure, helping to mitigate the recession's effects by improving connectivity by land, sea and air.

"Rail has performed particularly strongly, with more passengers than ever before now choosing to travel on Scotland's railways."

"However, this exercise has also confirmed that a fuller review of the NTS is required in the next Parliament which delves into more fundamental questions around how we can best work together and prioritise our activity to the benefit of Scotland's economy and Scotland's people."

Campaigners however said there has been no progress since 2007.

Colin Howden, Director of Transform Scotland, said: "It is tragic that there has been absolutely no progress over the past decade in moving people from cars on to public transport.

“As the new strategy sets out, the past decade has seen a 2% increase in traffic levels, while public transport use has declined by 6%.

"Whether one wants to tackle congestion, improve connectivity, or cut emissions, the evidence in this new strategy highlights a wasted decade in improving Scotland's transport."
